Access control methods for Bull FDA

You can use access control to restrict access from hosts and Storwize® V3500 clustered systems. You do not need to use access control to allow Storwize V3500 systems to use all of the defined logical units on the system.

Table 1 lists the access control methods that are available.

Table 1. Access control methods that are available
Method Description
Port Mode Allows access to logical units that you want to define on a per storage-system port basis. Storwize V3500 visibility (through switch zoning, physical cabling, and so on) must allow the Storwize V3500 system to have the same access from all nodes and the accessible storage system ports have been assigned the same set of logical units with the same logical unit number. This method of access control is not recommended for Storwize V3500 connections.
WWN Mode Allows access to logical units using the WWPN of each of the ports of an accessing host device. All WWPNs of all the Storwize V3500 nodes in the same system must be added to the list of linked paths in the storage system configuration. This list becomes the list of host Storwize V3500 ports for an LD Set or group of logical units. This method of access control allows sharing because different logical units can be accessed by other hosts.
